i just bought a nvidia GTS 450 and intalled it. The problem is that when i play a game every 5 or 10 secs the game lag ("cal caler" in creole) for 1 or 2 sec then its fine then again after 5 secs. this happens even with framerates over 100. i really dont know what is causing this can someone help me.

i dont know where i can see the response time of monitor but something strange happened todaywhen i play games in 3d stereoscopic (orange giving free 3d glasses) i dont get the problem its super bizarre lol
